So my 18 month old goes to bed at 6 and wakes up around 5:30-6:30 everyday. Recently (the past few days) hes been wide awake at 3-4am. He literally cries every 20 minutes until it’s time to wake up for the day. I thought it was his teeth (he’s getting molars right now) but I’ve given him Advil at night and it doesn’t help. He takes one nap during the day (1.5-2 hours long). He’s always nice and full before bed, and I’m sure to give him a nutritious dinner with food that won’t make him gassy/hyper. I’m so tired and don’t know what’s wrong😴 Help please!😩
